Aluminum-Shell Diaphragm Gas Meter
The Hangyu Xing aluminum-cased series of base meters is designed for measuring gases such as liquefied petroleum gas, natural gas, city gas, and chemical gases. This product boasts several standout features: compact size, elegant aesthetics, exceptional sensitivity, high measurement accuracy, excellent stability, robust reliability, superior resistance to high pressure and corrosion, and an extended service life—all coupled with convenient maintenance. The upper casing and main body of the mechanical aluminum-gas meter are both crafted using high-quality aluminum alloy die-casting, ensuring durability and precision. The exterior and interior surfaces of the housing undergo advanced anti-corrosion treatment, featuring outdoor-grade pure polyester powder coating that meets the stringent European RoHS environmental standards. Equipped with a 360-degree rotary valve, this meter minimizes friction while maintaining strong resistance against gas impurities and contaminants—a key factor in enhancing its overall sensitivity. Additionally, cutting-edge visual processing technology ensures clear, easy-to-read meter readings at a glance. With a wide measurement range, the meter accurately captures flow rates spanning from a minimal 0.016 m³/h up to a maximum of 6 m³/h. The valve seat and cover are made from advanced synthetic resins like phenolic compounds, offering enhanced wear resistance and improved long-term stability. Imported from Europe, the diaphragm material exhibits outstanding performance, easily enduring over 3 million flexure cycles and maintaining reliable functionality even in temperatures as low as -30°C. As a result, the meter delivers exceptional accuracy, smooth operational curves, and pressure losses that remain well below the internationally recognized limit of 200 Pa.
Core Features
• The housing is die-cast from aluminum alloy, featuring a simple assembly process and convenient maintenance.
• The transmission system uses gear drive, ensuring smoother and more balanced operation, eliminating deviations caused by moving parts, and delivering excellent consistency in repeated measurements.
• All shaft components are made from rust-resistant aluminum material to ensure corrosion resistance, while plastic parts are crafted from high-strength, corrosion-resistant synthetic engineering plastics to meet stringent strength requirements.
• Certified to OIML·R31 International Standard
